The Archbishop of Canterbury says the adoption of certain aspects of Sharia law in the UK "seems unavoidable".
Dr Rowan Williams told Radio 4's World at One that the UK has to "face up to the fact" that some of its citizens do not relate to the British legal system.
Dr Williams argues that adopting parts of Islamic Sharia law would help maintain social cohesion.
For example, Muslims could choose to have marital disputes or financial matters dealt with in a Sharia court.
